After a couple hours of work the A/C unit is installed
I also ran a new circuit for the A/C. Everything is working great and I can feel the cool air blow about half way up the bus. It was only in the high 60's or low 70's today so I couldn't really test how well it cools because it was already cool and the compressor didn't run but 1/4 of the time.
I sure am glad I installed it today rather than when it was 80+ because I was sweating my butt off as it was, lol.
I think it is going to work out well where it is. I will be sure to post an update the first chance I get to test it out.
